I’m having trouble installing my Classic Update/Highway kit using the schematic I found in the instructions.

The wiring schematic included with your kit is not meant to be used for installation instruction. In fact, if you were to attempt to wire the entire vehicle using only your schematic it would be somewhat difficult. We have attached the schematic to give an overall understanding of how each circuit is connected.

It is best to start wiring based on the kit section (denoted by letter….each letter will correspond with a section of your kit) suggested in the “Start Here” page of your instructions. This will walk you through each part of your installation with much more detail than you will find in a schematic. Doing this will not only make the job of rewiring feel much more approachable, but can help prevent installation based issues.
